Depending on the nutes being used doesn't hurt to have peroxide in the Res. Helps with dissolved oxygen and prevents root problems from starting. If using organics with any amount of microbial activity using peroxide is counter productive as it kills most everything. I got a link around here somewhere if anyone is interested. But bass is correct, using a chiller does more or less the same deal. Water at a low temp can hold more oxygen and prevents fungus or bacteria outbreaks.
